Abstract:
A projector includes an infrared generator, an infrared camera, an infrared control module, and a controller. The infrared generator provides an infrared curtain on a screen that the projector projects an image. The infrared camera detects a selection of an icon on a control strip located within the infrared curtain. The infrared control module is in communication with the infrared generator and the infrared camera, and determines a coordinate position within the infrared curtain associated with the selection of the icon on the control strip. The controller is in communication with the infrared control module, and determines a command for the projector based on the coordinate position of the selection of the icon, and executes the command.
